How to pass an array through routes.rb in Rails4?

Question

Ruby on Rails

I can not determine what is the problem in the database request, an error in the router or in the helper call? According to the logs, I suspect a router. Help!
Here is an example:
/-/-/-/-/-/.html.haml
...
- all_users_id = message_incoming | message_outgoing
- all_users_id.delete(user.id)
%h4= link_to "My Contacts", all_users_path(my_users_id: all_users_id)
routes.rb
get
'messages/all_my_users/:my_users_id', to: 'messages#all_my_users', as: ' all_users'
_____________________________________________________________________________
messages_controller.rb
def all_my_users
@my_users = User.where("id = ?", params[:
end
________________________________________________________________________

Answer 1

there is a special tag for formatting the code.
And according to your error, it is clearly written to you - ERROR: invalid input syntax for integer: "7/8"

Answer 2

7/8? :)

Answer 3

You cannot pass an array in a URL without additional gestures
. Usually, in Rails, arrays are passed in parameters like this:
http://myurl?array_name[]=7&array_name[]=8
